C, u. box or @use in xun mmmm ugo. the bywfie B and secured/therein.

D dmws a memberuns@ C reinforced by sm fi. from which exfvnd dww'af 0f i drum case to support the box C, mounted directly .above the rear axle lv. I

To provide for a constant and proper lubrication ofv the friction roll bearings, and

to protect the parts from rust the case may vbe filled with a suitable lubricant if desired.

Having indicated the'several parts by ref- @rence letters, the operation of the device will now be' explained.

it will be noted thatthe case C, is sup -ported in a'. fixed relation to the axle,and

' in other types ofvehicles in fixed relation to some other suitablel member thereof. lt

.l will thus ,be apparent that upon the compression of thespring K, as a result of the vehicle traveling over a rough road-tli'e bolts E, and link L, connecting the vehicle spring with the cross member l), will draw of a vehicle and its spring, a device of the character described com risinfr a frame adapted to be supported in a iixed relation -to said axle, a pair of coiled springs spaced apart mounted in the frame, a pair of semielliptic springs also mounted in the frame adapted to bear against each other-'their ends respectively overlapping the ends of the coiled springs, a cross member adapted to overlap the'end of the coiled springs, and means connecting said cross member with Vthe vehicle spring, whereby upon the latter spring being compressed due to the movement of the vehicle, the cross member will be drawn downward against the action of both the coiled and semifelliptic springs.

2. A device of the character described comprising a box vadapted to be supported in fixed relation to a member of a vehicle, a pair of coiled springs spaced apart within the box, a pa'ir of semi-elliptic springs `locatedr within the` box assembled in reversed .-,Ifor'der and bearing against each other, the

-ends of said springs overla ping the upper and lower ends of the coile springs, whereby they may act in unison, a movable cross member adapted toy act upon the springs' within the box to compress the latter, and means connecting said movable cross mem- I bei' with the spring of the vehicle.

v3, A device of' the character described comprising a box adapted to be suppcrted'in a fixed relation to a member of a vehicle, a pair of coiled springs spaced apart within the box, a pair of semi-elliptic springs located within the box assembledv in reverse order and bearing against each other, their ends overlapping the ends or the coiled springs, caps covering the ends of said coiled springs, suitable anti-friction rolls between said caps and the ends of the semi-elliptic springs, a movable cross -memb'er overlapping the ends of thesprings to compress the latter, anti-friction rolls between the ends V.of the upper semi-elliptic spring and the m'vable `cross member and also between the lower semi-elliptic spring and the bottom of the box, suitable bolts engaging the cross member projecting through openings in the bottom of the box, and a link connection adapted to connect the bolts with the spring of a vehicle.

4. A device of the character described comprising a box adapted to be supported by a member of a vehicle, a pair of coiled springs spaced apart within the box, an arcshaped spring having its ends bent parallel to the top of the box and overlapping the ends of the coil springs, whereby it may act in unison with the coiled springs, caps covering the endsv of the coiled springs,`anti friction bearings between the caps ,and the `ends of the arc-shaped springs, a movable cross member adapted to act upon the springs within the box to compress the latter, and means connecting said movable cross member with the spring of the vehicle.

5. A device of the character described comprising a box adapted to be supported by a member of a vehicle a pair of coiled springs spaced apart witliin the box, a pair of arc-shaped springs located within the box assembled in reversed order and bearing against each other, the ends of said springs bent to overlap the upperand lower ends of the coiled springs, whereby they may act in unison, a vmovable cross member adapted to act upon the springs within the box to compress the latter, bolts-connected with the movable cross member and looped around the arc shaped sprin s the end of the bolts projecting through t e bottom lof the box, and a link connection between the end of the bolts and the vehicle spring.

6. A device of the character described comprising a box'adapted to be supported in fixed relation to a member of a vehicle, a

pair of coiled-springs spaced apart within 'member with the spring of a vehicle.

7. A device of the character described comprising a box adapted to be supported in fixed relation toa member of a vehicle, a pair of coiled springs spaced apart within the box, a pair of arc-shaped springs having' their ends bent parallel tothe top and bot-` toni of tube box to overlap the ends of the coil springs whereby the springs may act in unison, anti-friction bearings between the ends of the ao-slieped springs and the ends of the coiled springs, :L movable member adapted to act upon 'the spiings Within the box, and a removable Wall for said box provided with inwardly projecting partition Wells adapted to partially inclose the coiled springs, whereby4 they may be insured 1o against accidental displacement.

In testimony whereof, I sign this specilioation inv the presence of two Witnesses.
